• Title: Quantum entropy and QCD factorization for low-$Q^2$ $ν$DIS
• Authors: Henry Bloss, Brandon Kriesten, T. J. Hobbs,
• Abstract summary: We introduce a novel approach based on the quantum entropy associated with continuous distributions in QCD, using it to characterize the limits of factorization theorems relevant for the description of neutrino DIS. This work suggests an additional avenue for dissecting factorization-breaking dynamics through the quantum entropy, which could also play a role in quantum simulations of related systems.

• Abstract: Deeply inelastic scattering (DIS) is an essential process for exploring the structure of visible matter and testing the standard model. At the same time, the theoretical interpretation of DIS measurements depends on QCD factorization theorems whose validity deteriorates at the lower values of $Q^2$ and $W^2$ typical of neutrino DIS in accelerator-based oscillation searches. For this reason, progress in understanding the origin and limits of QCD factorization is invaluable to the accuracy and precision of predictions for these upcoming neutrino experiments. In these short proceedings, we introduce a novel approach based on the quantum entropy associated with continuous distributions in QCD, using it to characterize the limits of factorization theorems relevant for the description of neutrino DIS. This work suggests an additional avenue for dissecting factorization-breaking dynamics through the quantum entropy, which could also play a role in quantum simulations of related systems.

  Double beta decays are rare nuclear processes that can occur in two modes: two-neutrino double beta decay and neutrinoless double beta decay. To draw reliable conclusions from their experimental constraints, it is necessary to have accurate predictions of the underlying hadronic interactions. This thesis provides formal prescriptions for double beta decays using the finite volume effects in the lattice QCD framework.

  We analyze the confinement of sine-Gordon solitons into mesonic bound states in a one-dimensional quantum electronic circuit(QEC) array. The interactions occurring naturally in the QEC array, due to tunneling of Cooper-pairs and pairs of Cooper-pairs, give rise to a non-integrable, interacting, lattice model of quantum rotors.

We propose the effective quantum neural tangent kernel (EQNTK) to quantify the convergence of QNNs towards the global optima.
